Torrey Pines Scientific’s WaferPlate Programmable Bake Plate features uniform heating across the surface of better than 1% over a heating range from room temperature to 350°C. It is ideal for precisely heating 12” (304.8 mm) and smaller silicon wafers, electronic chips, displays, adhesives, doing photoresists, and more.
The WaferPlate Model HP90 has a large circular 13.875” (352.4 mm) milled-flat plate aluminum surface. The unit is controllable remotely from a PC or industrial controller via the RS232 I/O port using the command set provided. Also provided is a benchtop controller, which is fully programmable—holding 5 routines of 10 steps each in memory for instant and repeatable recall and use. Each program can be made to repeat itself automatically from 1 to 98 times, or infinitely.
The plate surface can be set from room temperature to 350°C, and can be set and controlled directly to 1°C. Accuracy is better than1% of the heater setting over the entire range. Temperature sensing is by platinum RTD built into the heater plate. The HP90 has temperature ramping from 1°C/hour to 450°C/hour, count down timer with alarm and user settable Auto-Off and RS232 I/O port. The units are supplied with temperature calibration certificates traceable to NIST.
The WaferPlate Model HP90 is available in 100, 115, and 230 VAC, 1500 watts, 50/60 Hz models. ETL, CSA, and CE certification is pending.
